How to Solder Electronic Leads Together
Hello! This is Ross on behalf of expertvillage.com. In this clip, I am going to show you how to solder leads together. Each component has its own lead. So here I am going to use the helping hands. Then we will have them hold my wires here. That is all I really need, right now just get these wires up and I want to cross them over here and I want as much as surface contact between the wires as possible. It is called the mechanical connection. Now typically I would actually twist the connections on how that would might be preferred because a nice strong mechanical connections what you want and then the solder provides the good electrical connection in terms of conductor because that is conductor. When I solder what is important here is that I need it to flow into the connection points. So solder is really all about flowing all these molten stuff. I am going to just pull the solder on, make sure I have got a good coverage on my iron and then I am going to put just a drop as I start. I am going to heat from the bottom even. As I heat I am going to apply the solders from the top of the components and pull the soldering iron another way when it is done. You can see what happened is that the heat transferred through here to the bottom of the component I was soldering and in this case two pieces of wire, I apply the solder to the other side that solder will only get sucked down in there is as it is hard enough to flow. We need to have enough heat to make the connections so that is what you want to do to get good flow through. You can see here to get solder on and if it is really a good connection, it is not going to come apart, now if I had a mechanical connection to that, I can even make it stronger, but the solder is strong. If I did not have good flow for the solder then it might just fall apart so you can test the connection at home.
